A hub interchange completed on May 29, 2017 in mountainous Chongqing city has startled the Internet with its range upon range of roads and outlets. The five-story structure Huangjuewan Flyover connecting more than 20 ramps is the largest, most complicated and functional hub interchange in China’s southwest area. It has aroused widespread attention since its construction work started in 2009. The flyover, depicted as “the city’s blood vessel”, links roads in eight directions including Guangyang Isle, Chongqing Jiangbei International Airport, Grand Buddha Temple Bridge, Chaotianmen Bridge, Danzishi, Sigongli and the Tea Garden area. Confused netizens said it would be a great challenge to any navigation system. (Photo: China News Service/Chen Chao)
